One if the rulers after Jesus was born was told to kill off Christians, but he countered with somethig like, "if it's nothing, it will die out on it's own, if it's real, I don't want to be the one who goes against God."
Some people have tried to squash bitcoin, but they can't. China tried to ban it, but that didn't work. Anyone who actually gets it would put their own money in even if they just want more dollars.
It wouldn't surprise me if it's something similar to how the ruler thought about Christianity. If Bitcoin is real, we can't stop it anyways, and if it's not, it will crash and die on it's own.
